Scope

GB/T 47758-2026 is the English-translated version of 模具随形冷却镶件.

GB/T 47758-2026 covers conformal cooling inserts for moulds. It classifies the inserts and sets technical requirements for design elements, CAE simulation analysis and performance verification, inlay materials and post-processing.

Matching test methods address the geometric elements, the simulation, the inlay materials and the inlay quality, and the standard adds inspection rules together with requirements for marking, packaging, transport and storage.

It applies to the manufacture of conformal cooling inserts for injection moulds and die casting moulds, and is aimed mainly at inserts made by laser powder bed fusion additive manufacturing of metal. Issued on 2 July 2026 and applicable from 1 February 2027.
